| Without any warning the abs electronic control module went out on my 2001, s-10 blazer. the malfunction caused what is known as pump run on. this means that the abs pump runs constantly and has to be replaced. removing 2 fuses disables the pump but does not turn off the abs warning light on the instrument panel. the vehicle can be driven but only has power brakes and will not pass a safety inspection. after doing some research on the internet it was discovered that this is a common occurrence on gm vehicles. especially trucks and suv's. the dealerships want @ $700 to repair this issue. the part can be removed and sent off to several places that will rebuild the product for @ $150. shouldn't gm do something about the faulty components that they use on their vehicles. ie: get the part from another manufacturer or make the manufacturer responsible for their product. it seems that gm and the manufacturer make out like bandits on this deal. my vehicle only has 70,000 miles on it and is well taken care of. this part should not have failed in such a short bit of time. | |||

| Brake pedal went all the way to the floor while stopping, my wife was almost hit by a bus. the dealer has been trying to identify the problem, an has thus far replaced the master cylinder. the problem still exists intermittently, and causing the anti-lock brake pump to cycle (locking the brakes) alleviates the low or fading pedal for a short period of time. this problem seems to be related to the abs pump and/or the computer controlling it. i am very experienced in diagnostics and rebuilding automobiles, and have seen this occur on other makes and models (usually a failure of the abs pump). my car will be back at the dealer again on tuesday april 14th for this on going failure of this poorly designed abs. maybe my government will do something about this when the brakes on this vehicle kill some innocent citizen or government employee driving one of these cars. *jb | |||

| In three different occasions, 2 in 06 and 2 in 07 the brakes failed to stop it's an intermittent incident. in 06 after incident, master cylinder brake was changed (not keep old part). after third incident, i took it to dealer. their response was nothing wrong. but on my interview with head technician, mentioned that could be the abs activating, like reading false instructions. what could be done, he said to change the sensors but there were three on the car and those were expensive and then there are more other components to the abs that could also be the cause of failure. i started to investigate on the internet to understand the abs and then to see if i was the only one, and then looking for recalls. i came to an article that described the failure exactly as it has happened to me all these past events and reads:...sidebar: what are the most common failures with abs that you have detected from your vehicle inspections? folck: well, in the general motors trucks and vans, the 4-wheel kelsey-hayes antilock brake system. the brake pedal is supposed to just pulsate a little bit and stay in position, but sometimes it goes to the floor. sidebar: what does that indicate when it goes to the floor? folck: that there is a failure in the abs. they have a problem with their algorithm, and it won?t set a failure code in the kelsey-hayes 4-wheel. in laymen?s terms, an algorithm is a sequence of functions the computer is supposed to take. there are glitches in the algorithm, and gm has acknowledged the algorithm failures. (eds. note: see the article in the money section of usa today, gm: computer glitch could affect brakes, 05/22/98.) ... first of all, my safety is first and the manufacturer has to fix this problem right away. i am not in the position of selling the car since i am still paying dearly for it and second, i would not like to pass this problem to someone else. *tr | |||

| I was in a drive through which looped around the building. i applied the brake to stop at the window and could feel the abs engage and the vehicle did not want to stop. it scared me and of course i reapplied the brake quickly, to avoid hitting the vehicle in front of me, and i was finally able to stop. this happened again a few weeks later at a large intersection at a red light. i was 7 months pregnant at the time and was pretty scared. i have heard several of these complaints and i know that the brakes on every year before this were recalled. i also had trouble with the brake lights and four-ways, which stopped working. i was driving and the four ways came on. i had to pull over and ended up holding the button down while i drove in order for them to stop flashing. shortly after the turn signals stopped working. finally, the speedometer temporarily stopped working, then shortly after that, the heat stopped working, the vehicle only blowing cold air. we replaced the thermostat but the heat still would not function. i ended up getting rid of the vehicle because of the numerous malfunctions. *jb | |||

| 1) abs and e-brake light continually come on; unsure if abs system is functional; i have had the computer tested and it returned no faults 2) side windows work intermittently; no explanation; windows will not roll down for days at a time and then they work fine for days at a time 3) sunroof no longer functional; chevy dealer said the heat warped the internal parts and they broke as i rolled it back; weather was mild and the breakage happened at 0500 in the am; i don't believe it was heat related 4) rear of vehicle is has drastically fallen below the front; i have no explanation as to why; it looks as if the vehicle front suspension was raised and the rear was lowered; drives fine, but feels unsafe all of the above happened shortly after the warranty expired, between 40000-50000 miles. *nm | |||

| Not only have i had problems early with hub and bearing-- and also replaced ball bearing-- now the abs-- manufacturers has done poor job on brake. wheel parts- very cheap parts-- many talk about it and know that the blazer has had problems with these parts. my family has purchased chevy's for years-- i am now never about to purchase a chevy again. while i pay my car payment, i always purchase new. i am always also paying for work done on this vehicle, and i am talking- over 2,000 so far and again have to go in today-- i may even trade it in i am so pissed. we also had problems with my husbands truck..i don't know what they did, or who they purchased their parts from, but surely went to cheap parts, they( chevy) put many consumers in a bad spot. and i have written a complaint before- when i had the chevy blazer 2001 for a year half. they seem to want to only hear if i died cause of the failures that it would be looked into. *jb | |||

| On 11/20/01 i pressed brake pedal to floor but my brakes failed causing my vehicle to bump a vehicle in front of me (bumped vehicle at very slow speed due to heavy stop and go traffic). i initially thought that my foot merely slipped off the brake pedal as after the incident my brakes worked properly. however, on the following day (11/21/01) my brakes failed a second time. i had to swerve onto the shoulder of the road in order to avoid an accident and was finally able to get my vehicle stopped. after a short period of time, my brakes were operational again. at that point, the vehicle was taken to the closest chevy dealership (heritage auto plaza in alexandria, va) where it remains as of 10:05 a.m. on 11/26/01. *ak | |||

| Our 2001 chevy blazer required brake service with 44000 miles. we selected tuffy auto service centers (warren, mi), our estimated cost was $180. during the brake service the tuffy service manager informed us that our rear brakes would require replacement, our cost for the rear was an additional $280. the service manager indicated that the rear brake disc-rotors were heavily corroded, service (rotor turning) was not an option and replacement required. rear brake service at 44000 miles is highly unexpected, full replacement due to corrosion is unacceptable. our assessment is that the disc-rotor material was not correctly specified (and/or perhaps a galvanic corrosion with aluminum wheels/iron hubs), the resulting excessive corrosion unexpected and a serious safety concern. *ak | |||

| On the 10 of july i took my 2001 chevy blazer in for routine brake service, i was then told by my mechanic(satch whitt) that i had 4 defective rotors that needed to be replaced, that they appeared to be defective. he stated that the metal was just flaking off and to him it appeared that they had been made from reprocessed metal. he also stated that he had seen alot of this in the newer chevy products recently. although i was lucky and did not have an accident i feel that this is a very real safety concern for american families. i have kept the rotors in hopes that chevrolet would stand behind thier product. thank you for your time and consideration in this safety matter, mark wiley. *ak | |||
